At the end of 2019 and before 2020 began, most realists knew the team needed to clear the books and start over. They knew it was going to be a rebuild from the ground up and that meant player development and building the roster from scratch...that meant losing and building it all back up.
Most realists also knew Tom was going to the best team possible in Tampa and he was going to win there with those super weapons and tough defensive front. Most of us really wanted to enjoy the rebuild and take pleasure in watching from afar as Tom won at least one more ring and enjoy talking about both of those things.
Bottom line is both the rebuild and the Brady finale could not be enjoyed, because the Brady zealots insisted on derailing every thread and telling us how terrible everything was here and how we could have been living the success Tampa was enjoying. As if had Tom stuck around suddenly all our salary cap problems from going all in the last five years would be instantly solved, all our aged or overly expensive players would suddenly be replaced with Mike Evans, Chris Godwin, Devin White, Vita Via and the rest for free.
This ^ of course is a pipe dream, had Tom stayed the 2020 team would have been worse than the 2019 team because the salary cap exists. So they would have eaten garbage for a year while they fixed their cap, wasting a whole year of Tom's dwindling time left in the league or borrowed more and the Brady era in New England would have ended in a whimper and the delirious Brady stans among us would have blamed BB for not spending money that he didn't have.
It's a real sense of entitlement that New England fans have that they think they're supposed to win a championship every year otherwise they're being cheated. Some handle it with grace and understand football, salary cap and roster building.... others don't understand that much and attribute it all to one magical player. Those people wound up with their own safe space because the rest of us understood the situation and were willing to deal with it... but weren't willing to deal with the histrionics and whining.
